As a result, antibiotic resistance now ranks among the gravest medical problems of modern times. Good Germs, Bad Germs addresses not only this issue but also what has become known as the "hygiene hypothesis"-- an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders. In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic relationship between the human body and its resident microbes--which outnumber its human cells by a factor of nine to one! The book also offers a hopeful look into a future in which antibiotics will be designed and used more wisely, and beyond that, to a day when we may replace antibacterial drugs and cleansers with bacterial ones--each custom-designed for maximum health benefits.

    Mankind's battle to stay alive and healthy for as long as possible is our oldest, most universal struggle. With his characteristic wit and vastly informed historical scope, Roy Porter examines the war fought between disease and doctors on the battleground of the flesh from ancient times to the present. He explores the many ingenious ways in which we have attempted to overcome disease through the ages: the changing role of doctors, from ancient healers, apothecaries, and blood-letters to today's professionals; the array of drugs, from Ayurvedic remedies to the launch of Viagra; the advances in surgery, from amputations performed by barbers without anesthetic to today's sophisticated transplants; and the transformation of hospitals from Christian places of convalescence to modern medical powerhouses. Cleverly illustrated with historic line drawings, the chronic ailments of humanity provide vivid anecdotes for Porter's enlightening story of medicine's efforts to prevail over a formidable and ever-changing adversary.

    We now understand more about aging—and how to prevent and reverse it—than ever before.In recent years, our understanding of the nature of aging has grown exponentially, and dramatic life extension—even age reversal—has moved from science fiction to real possibility.Dr. Michael Fossel has been in the forefront of aging research for decades and is the author of the definitive textbook on human aging. In The Telomerase Revolution, he takes us on a detailed but highly accessible scientific journey, providing startling insights into the nature of human aging.On first examination, aging appears inevitable and straight-forward. Everything, after all, from mountains and galaxies, to plants and animals, ages, doesn’t it? Not exactly. With deeper consideration, aging turns out to be complex, and surprising questions emerge:Is aging something that happens within our cells or in the organism as a whole?Why do some cells age every time they reproduce, while others can reproduce indefinitely, without signs of aging?How close are we to being able to dramatically extend life-spans and cure age-related diseases such as Alzheimer’s, dementia, and strokes?Instead of the common idea that “we accumulate damage, therefore we age,” the reality is the opposite: our cells age and so we begin to accumulate damage. The latest research shows so-called “ageless” cells contain “telomerase”—an enzyme that maintains telomeres and adds back segments lost during replication. Essentially, it is the telomere that controls how well our cells repair themselves over time.The Telomerase Revolution explains simply how we came to understand the ways aging and age-related diseases work, what we can do about them now, what we will be able to do to cure and prevent these diseases—and why we are now on the brink of a revolution in human medicine.

    At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions & bitter rivalries. With humility unspoiled by false modesty, Watson relates his & Crick's desperate efforts to beat Linus Pauling to the Holy Grail of life sciences, the identification of the basic building block of life. Never has a scientist been so truthful in capturing in words the flavor of his work.
